Problems solved by technology
[0005] Existing accumulators can only store energy in one direction due to design problems, and regulating valves, as a connection with control capabilities, are sometimes connected in two-way flow pipelines, and in two-way flow pipelines, In order to protect the regulating valve and make the regulating valve work normally, two accumulators need to be installed, which will cause the volume of the regulating valve to become larger and affect the normal assembly of the regulating valve

Embodiment 1
[0044] see Figure 1-2 , an energy storage type two-way pressure regulating valve, including a two-way regulating valve casing 1, and an inlet A2, an inlet B3 and a piston passage 4 are dug on the two-way regulating valve casing 1, and the inside of the two-way regulating valve casing 1 passes through the inlet A2, the inlet B3 and the piston Road 4 is connected with the outside world, and the entrance A2 matches the entrance B3. A sealing piston 5 matching itself is placed in the piston road 4. The upper end of the sealing piston 5 is connected with a torsion bar 6, which is far away from the sealing piston 5. One end runs through the piston passage 4 and extends to the outside of the two-way control valve housing 1. The end of the torsion bar 6 away from the sealing piston 5 is connected to a turntable 7. The turntable 7 is convenient for the staff to adjust the sealing piston 5. The two-way control valve housing 1 is connected with Two-way energy storage ring 8, the two-way...

The invention discloses an energy-accumulation bidirectional pressure regulation valve, and belongs to the field of bidirectional regulation valves. According to the energy-storage bidirectional pressure regulation valve, the influence of a pressure generated by fluid in a pipeline on the regulation valve is reduced through bidirectional energy accumulators when the regulation valve is used for quick regulation; because the bidirectional energy accumulators are completely symmetrical in layout, the two bidirectional energy accumulators both can bear a load uniformly, the wear of the two bidirectional energy accumulators is approximately the same, and situation that the working life of the regulation valve is shortened due to excessive wear of one bidirectional energy accumulator caused bylayout of the bidirectional energy accumulators is unlikely to occur; and the two bidirectional energy accumulators work cooperatively to reduce the impact to the regulation valve, so that scouring losses, caused by high-pressure fluid, of the inner wall of the regulation valve and the energy accumulators are minimized, work losses of the regulation valve and the energy accumulators during normalwork are greatly reduced, the service life of the regulation valve and the energy accumulators is prolonged, and daily maintenance work of workers is reduced.
Description
technical field [0001] The invention relates to the field of two-way regulating valves, in particular to an energy storage type two-way pressure regulating valve. Background technique [0002] Regulating valve, also known as control valve, is the final control element used in the field of industrial automation process control to change the process parameters such as medium flow, pressure, temperature and liquid level by means of power operation by receiving the control signal output by the regulating control unit. Generally, it is composed of an actuator and a valve. According to the stroke characteristics, the regulating valve can be divided into straight stroke and angular stroke. [0003] The accumulator is an energy storage device in the hydraulic pneumatic system. It converts the energy in the system into compression energy or potential energy at an appropriate time and stores it. When the system needs it, it converts the compression energy or potential energy into hydr...
